644f0c0e05 - Add a name to VMFunction so that the disassembly can be more informative.

bee4c3e760 - Added functions for converting the AST to text. This is not hooked in anywhere yet, since
the parser currently just throws the AST away.

4b8900816b - Make the ZCC parser compilable again. Does every rule in the grammar that needs to appear in
the AST do so now? That would sure be nice.

081ebbb64b - I have decided to opt for simplicity over C-like-ness and group array sizes with the rest
of the type declaration rather than split it up after the variable name.
- More AST work. At this rate, maybe I'll finally be building a complete AST by the end of the
  month!

c043627cc1 - Some abstract syntax tree creation stuff. (Plus some tentative type creation stuff that made
me realize I would be better off creating a type-agnostic AST for the entire input instead
  of trying to tentatively create types before they're seen.)

f88f601230 - Removed the third parameter from dumpclasses when it was restricted it to Actors, because
I have no idea what that was all about.
- Got rid of FActorInfo and merged it into a new PClassActor.

6f1bf257e9 - State code now properly calls action functions and has a RET instruction. As expected,
running with the checked VM can be quite slow, since it has asserts everywhere. Some other
  fixes were needed before the code actually worked:
  - A_CallSpecial needs to have its arguments cast to ints.
  - Some functions that set pnum/paramnum directly did not decrement it by 1. This also applies
    to A_Jump, though it just uses the value of paramnum instead of changing it.
  - Renamed pnum in the PARAM macros to paramnum, since pnum is already used in a few other
    places for something different, so this makes searching for it easier.
  This has not been tested especially thoroughly, but a first glance seems to indicate success.

739e684549 - Converted all action functions be directly callable by the VM (though they are not yet
usable).

7ea11cd169 - Allocate VM script code and constants in a single block for better locality of
reference.

e5ef25591d - Use a union, rather than pointer aliasing, to access the parts of a VM instruction.

c424c61ffc - Added fixed registers that won't be freed automatically, so that parameters
can actually be used. In the end, all temporaries should be assigned to
  unique virtual registers, and a register allocator can alias them to real
  registers, but as long as we don't do any CSE, this is good enough for now.

3cbac657d6 - Added type coercion for action function parameters.
- I add PARAMI, and then I don't even do it right...

126c738116 - Added PARAMI for the common case of passing an integer constant to a function.
- Made FxParameter::Emit free its operand's register.

caa5f6dbdc - Send disassembly to a file, since it gets way too slow when sending a disassembly
of every single thing to the rich edit control.

85cc335725 - Added dummy code generation for states that pass parameters to action functions.
Currently, they're only good for disassembly and pasting into a proper text editor
  for viewing.
- Fixed some problems with the FxExpression emitters that were revealed by actually
  using them on the standard actors.

3001708d16 - Added some code for generating VM code from FxExpressions. This is completely untested, since
it isn't even used anywhere yet. In retrospect, I probably should have targeted an intermediate
  representation and done codegen with that instead, since that would be something I can reuse.

3e7b69a12e - All states now use thunk functions to call the action functions. This is the bare
minimum to be able to say that VM is being used.
- Added tags for the pointer constants table.

1eb7912bd8 - Make the autosegs read-only.
- Derive PClass from dobject.cpp. This has one major ramification: Since the PClass
  is not allocated until runtime, you cannot initialize any static/global data
  structures with pointers to PClasses using RUNTIME_CLASS. Attempting to do so
  will just initialize with a NULL pointer. Instead, you can initialize using
  the address of the pointer returned by RUNTIME_CLASS and dereference that. By
  the time you have an opportunity to dereference it, it will no longer be NULL.
- Sync CmakeLists.txt.
- Random fixes for problems GCC spotted.
